Uncover Your Accomplishments
There are many accomplishments in life that are often overlooked as being accomplishments. For example, developing your character is a great accomplishment. Maimonides writes that this is a fulfillment of the mitzvah to walk in God's ways.
Each difficulty that you cope well with is an accomplishment.
Doing an act of kindness for another person is an accomplishment. (And the less you feel like doing it, the greater the accomplishment!)
